It is a known issue that is really no issue at all.. I talked to my cousin about a loud injector and he pulled a bulliten on it.. it is just because of the bends in the injector line..

It's perfectly normal. All CR's I've been around do it.

 

yes all common rails will have that, and it is not necessarily just the number one, could be different on any truck, remember with our trucks along with rail pressure and timing, they also add injector pulse, could be that you can feel the number one pulsing, in the fuel line, but not the others.... and the tick you hear is very normal... nothing to worry about there....

 

Maybe there's someone inside it
